Abstract

Data include results from water isotope analyses (one *.csv file) for samples collected in Utqiagvik (Barrow), Alaska during August and September 2012. Samples were from surface and soil pore waters from 17 drainages that could be interlake (basins with polygonal terrain), different-aged drain thaw lake basins (young, medium, old, or ancient), or a combination of different aged basins. Samples taken in different drainage flow types at three different depths at each location in and around the Barrow Environmental Observatory. Precipitation stable isotope data are also included (added in October 2019 with no changes to previously released data). This dataset used in Throckmorton, et.al. 2016.

The Next-Generation Ecosystem Experiments: Arctic (NGEE Arctic), was a 10-year research effort (2012-2022) to reduce uncertainty in Earth System Models by developing a predictive understanding of carbon-rich Arctic ecosystems and feedbacks to climate. NGEE Arctic was supported by the Department of Energy’s Office of Biological and Environmental Research.

The NGEE Arctic project had two field research sites: 1) located within the Arctic polygonal tundra coastal region on the Barrow Environmental Observatory (BEO) and the North Slope near Utqiagvik (Barrow), Alaska and 2) multiple areas on the discontinuous permafrost region of the Seward Peninsula north of Nome, Alaska.

Through observations, experiments, and synthesis with existing datasets, NGEE Arctic provided an enhanced knowledge base for multi-scale modeling and contributed to improved process representation at global pan-Arctic scales within the Department of Energy’s Earth system Model (the Energy Exascale Earth System Model, or E3SM), and specifically within the E3SM Land Model component (ELM).

Methodology
For the water collection, surface waters were collected as grab samples from the edges of drainages. For shallow active layer samples, one stainless steel drive point sampler was installed at each sampling location. Tubing was installed into the drive point opening, and water was slowly siphoned into 1 L bottles using a hand-pump vacuum. For the collection of deeper samples, 14-20 macro-rhizon samplers were installed in an array down to the frost table. For unsaturated soils, pore water was collected using fibreglass wick samplers. Precipitation samples were collected using a simple funnel and collection bottle at multiple sites around the Barrow area. These collectors were sampled on a regular basis to avoid any post-precipitation evaporation effects. Because of low sample volumes both isotopes were not run for some samples. GNIP data are from the IAEA/WMO Global Network of Isotopes in Precipitation database (http://www.iaea.org/water). Laboratory analyses were performed using EPA and other standard published methods. Location measurements were taken with a hand-held GPS (plus/minus 3m accuracy) using NAD 83 UTM Zone 4N.
